About This Medication
# ArdelyxAssist Patient Guide: How to Get IBSRELA (tenapanor) at Low or No Cost IBSRELA (tenapanor) is a prescription medication used to treat irritable bowel syndrome with constipation (IBS-C) in adults, helping relieve constipation, belly pain, and bloating by working differently from other treatments.[1][2][5] This guide explains the **ArdelyxAssist** program from manufacturer **Ardelyx**, which offers support for eligible patients to access IBSRELA at low or no cost, including a copay program for commercially insured patients and additional help for uninsured or underinsured individuals.[1][2] ## Who Qualifies for ArdelyxAssist? ArdelyxAssist provides affordability support through programs like the **IBSRELA Copay Program** and other assistance for those who can't afford their medication.[1] Eligibility focuses on insurance type rather than strict income limits, making it accessible for many adults with IBS-C. ### Key Eligibility Criteria - **Age and Diagnosis**: Adults (18+) with a confirmed IBS-C diagnosis (ICD-10: K58.1). IBSRELA is not approved for children under 18.[1][5] - **Insurance Status**: Primarily for patients with **commercial (private) insurance** where IBSRELA is covered. Excludes government plans.[1] - **Income Considerations**: No specific federal poverty level (FPL) thresholds are publicly detailed, but additional support is available for uninsured or underinsured patients unable to afford IBSRELA. Contact ArdelyxAssist for personalized assessment.[1][4] ## About IBSRELA (tenapanor) **IBSRELA** is taken as 50 mg twice daily (BID) to treat **IBS-C**, a condition causing abdominal pain, bloating, and constipation.[1][2] Unlike laxatives, it targets sodium-hydrogen exchanger 3 (NHE3) in the gut to increase fluid secretion and ease bowel movements.[2] - **Common Side Effects**: Diarrhea (most frequent), abdominal distention, flatulence, and dizziness. Severe diarrhea may occur; do not take two doses at once.[1] - **Important Warnings**: Not for children under 6 (may harm them); use caution if under 18. Tell your doctor about all medications.[1][5][9] - **Cost Without Assistance**: Approximately $2,000–$2,500 for a 30-day supply (60 tablets), or up to $30,000 annually.[4][8] With ArdelyxAssist, **commercially insured patients** can pay as little as **$0** per 30- or 90-day prescription.[1][2][6] ## Income Eligibility Breakdown ArdelyxAssist does not publish fixed income thresholds like many programs (e.g., 400–500% FPL). Instead: | Household Size | Typical Income Limit (if FPL-based, estimated) | Notes | |---------------|-----------------------------------------------|-------| | Individual | Not specified; case-by-case for uninsured/underinsured | Commercial copay has no income requirement [1] | | Couple | Not specified | Focus on affordability assessment [1] | | Family of 3 | Not specified | Call for evaluation [2] | | Family of 4 | Not specified | Excludes government insurance [1] | **Notes**: The copay program requires no income proof for eligible commercial plans. Uninsured/underinsured patients may qualify for free or discounted IBSRELA via ArdelyxAssist after review—no public FPL cap listed.[1][4] Always verify with 1-844-427-7352.[1][2] ## Insurance Requirements - **Accepted**: **Commercial insurance only** (e.g., employer plans, marketplace plans under ACA, excluding certain federal ones like MHBP or FEP).[1][6] - **Excluded**: Medicare (Parts B/C/D), Medicaid, Medigap, VA, DOD, Tricare, CHAMPUS, state assistance, or any government-funded plans. IBSRELA must be covered by your plan.[1] - **Tip**: Check your formulary; prior authorization may be needed. Use the IBSRELA Pharmacy Network for easiest access.[1][4] ## Step-by-Step Application Process 1. **Get Prescribed**: Ask your doctor for IBSRELA 50 mg BID. E-prescribe to an IBSRELA Pharmacy Network location or any participating pharmacy.[1] 2. **Check Eligibility**: Confirm commercial insurance and no government coverage.

Auto-applied for eligible fills.[1][2][6] 4. **For Uninsured/Underinsured**: Call ArdelyxAssist at **(844) 427-7352**.
